It was supposed to be a simple remodel. She didn't plan on finding buried treasure . . . or looking down the barrel of a gun. Agatha Lapp is elated when Channel 4 News decides to run a feature story on Amish businesses. The extra publicity should guarantee even more success for her Plain and Simple B&B, especially after she's finished with the remodel. The cameras are rolling live when Agatha raises the rubber mallet and punches the first hole in her living room wall. That's when things get complicated . . . Hidden inside the wall is a diamond-studded belt buckle stolen twenty years earlier. The police return the buckle to the owners and refuse to re-open the case. When overzealous treasure hunters break into the B&B and a dead body is found half a mile down the road, Agatha knows she needs to take this investigation into her own hands. With the help of a retired detective and her best friend, Agatha sets out to solve the mystery of the Lost Texas Treasures and find a killer. Their chase leads them to the famed YO Ranch where Agatha finds herself looking down the barrel of a gun. Suddenly, she's no longer worried about a remodel. She just wants to live through this showdown.
